Prop thoughts

I went and did it. Had my 520 conv on a light 12' hull will Quickslick that would go anywhere. Wanted a family ride boat so changed it over to a 14.5' Viking with rodboxes and poly (heavy!!!). Got stuck a couple times on maiden trip (did have 950# of people and cooler in it). Still ran the hill but ...

Re: Poly bolt spacing

Thanks southern, that's exactly what I was looking for. I'll stick with 6x6 or less depending on stringer location. I sometimes drive my boat like it's a four wheeler so I may go down to 5x5. Nice job on the poly by the way.

Poly bolt spacing

Couldn't get the time so I went ahead and had a local guy replace my stringers. By the way if anyone in the Pasco county area needs glass work done this guy is top notch. Worked for Stamas for 20 something yrs, retired and now has a shop in his back yard for side jobs. Bet his stringers or repair wo...

Re: Paint or gel coat inside glass hull?

You don't need much, 1.5hp/6 gallon compressor would probably do. Just need a regulator either on the gun or on the compressor to knock the pressure down around 40-50 psi. I do recommend hitting your existing gel coat with sandpaper and/or acetone to get the wax off so it will adhere better. I've no...

Re: Paint or gel coat inside glass hull?

Yes you can re-rivet it. As for spraying gel, you can spray from a gravity fed gun. I use this el-cheapo from HF. It sprays gel fine. You can also use it to spray your webbing, I geled and webbed one today. No reason to add wax to your webbing/gel mix(50/50), just mix it hot (8-10cc per pint) and sp...

Re: Lycoming 4 cyl cruising rpm

Aircraft engines are designed to run at a continuous RPM of 2500-3000 depending on motor. Your 360 can run at 2750 all day. With that said though both boats are pretty big for those engines hauling tools or gear. JMO

Re: Stringer material?

I went white pine. I've resined them real good. Gonna do mat then a few layers of biaxial cloth/mat. Just not sure how many layers I should do. Thinking 1 mat and 2 cloth/mat. Didn't know if I should do a 4th layer. That biaxial stuff is suppose to be pretty dang strong. Thanks for any advice.

Re: Stringer material?

Regular old spruce pine huh? That will make it cheap. I had heard a recommendation of cedar but I was dreading trying to find that in 2x4x12 and then what it would cost. Thanks for the info.

Got a new baby on the way so I'm gonna convert my boat over to a more family friendly ride boat. I'm gonna change hulls to a 15' viking with rod boxes. I've had it in the back yard for awhile because it needs stringers. Has 2x4 stringers now. Any opinions on best wood/material to use, would like to ...

That's a lot of oil but not unheard of on a gpu. That motor is just a non-flying aircraft engine so anyone that has ever done a top end on an aircraft engine can do it. Super simple job. Ducurra aviation will have all the parts necessary. No idea on price up there but it's probably a little more tha...

Re: 8cyl gpu convert or not

Before JC Stanley passed (the original gpu converter) I was talking to him about this. He said the torque was unreal. He did say it loved fuel but you would have 400hp with some serious torque. My experience with gpu cranks are that they are plenty strong...until they are turned.

Granted I've got a 520 conversion but cylinders are the same. I have had both down draft and up draft on mine. I felt like the downdraft (had a holley 500, then a edelbrock 600) rapped up quicker, but the down draft ran smoother and burnt less fuel. No difference in HP I can tell. helicsher, if your...
